gem environment , sudo gem environment give same result:

rubygems environment:   - rubygems version: 1.5.3   - ruby version: 1.8.7 (2011-12-28 patchlevel 357) [x86_64-linux]   - installation directory: /usr/local/lib/ruby/gems/1.8   - ruby executable: /usr/local/bin/ruby   - executable directory: /usr/local/bin   - rubygems platforms:     - ruby     - x86_64-linux   - gem paths:      - /usr/local/lib/ruby/gems/1.8      - /home/ava/.gem/ruby/1.8   - gem configuration:      - :update_sources => true      - :verbose => true      - :benchmark => false      - :backtrace => false      - :bulk_threshold => 1000   - remote sources:      - http://rubygems.org/ 

rvm -v : rvm 1.22.3

ruby -v : ruby 1.8.7

osx 10.8.4

echo $path /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/ava/.rvm/bin:/home/ava/bin

gem install <gem-name> gives

if have installed rvm root user, must sudo install anything.

you can install rvm in user-mode regular user, in case stored in home directory , no sudo required.

if not committed particular install, type sudo rvm implode , start over.
